专门充加速器来发差评,傻逼作者,你是不是以为你特别会做关卡,抵挡波次没有加速只能硬等。没有读档功能是最傻逼的,这意味着你玩半个多小时一个多小时一不留神就被僵尸后入了,然后你要从0开始继续玩,这个傻逼游戏初期又贼几把漫长,草泥马的。我从未见过有任何一个游戏失败带来的负反馈这么大的。♥♥♥♥
Это лучшая стратегия в жанре Tower Defence в реальном времени. Я большой поклонник серии игр Kingdom Rush от моих любимых Iron Hide и эта игра является превосходной реализацией данного жанра. Нескончаемые волны зомби, ощущение неизбежности, шок от количества самих зомби, бесконечная стрельба, сдача позиций одна за другой... идеально! Я даже не расстроен, что к игре перестали выходить обновления, потому что она достигла своего идеала и накручивать её дальше - только портить. Игра немного требовательна к процессору при больших волнах зомби.

创意工坊里面很多地图可以玩,很多样性
Наиграл в общей сложности в эту игру за 300 часов. Перепрохожу стабильно раз в полгода. Хороший, годный сплав тавердефа и экономической стратегии, много приятных мелочей вроде древа развития и достаточно хардкорных одиночных миссий в кампании. Видно, что, разрабы долго полировали механики и баланс. К слову, имеет место реализация самых отбитых стратегий умерщвления зомби, что повышает реиграбельность и удерживает интерес. Если случится чудо - попробовал бы когда-нибудь либо кооп, либо продолжение, т.к. уже давненько настолько не залипал в подобные тайтлы.
